IMPROVEMENT IN MULE FOR SPINNING.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

\ Be it known that I, JOHN CMNOCK, of Salmon Falls, in the county of Straiford, and State of New Hampshire, have invented a new and useful Mechanism for Operating the'Car-riageo' a Spinning-Mule; and do hereby declare the same to be fullyY described in the following specification, and represented in the accompanying drawings, of which- Figure l is a top view, and

Figure 2 a longitudinal sectionof a portion ofthe frame land carriage of a mule, with my invention applied thereto. l

The carriage may he said to be running in, while going toward the draw-rollers, and running out when going from them. In running out, a regular speed or movement of equal distances in equal times is desirable,'because the draught and spinning of the yarns then take place. When the carriage is running in, however, it is desirable to have a quick motion, attended with a gradual coming to rest, in order to prevent the carriage from rebounding, so as to break or injure the yarns. My invention is intended to produce such motions of the carriage. Y

In the drawings, A denotes the'mule-frame, and B the carriage, the spindles and draught-rollers not being shown. The carriage is supported by several wheels, a a, resting on rails b b b. A chain, @connected at its .two ends to the carriage, passes under and against a toothed driving or sprocket-wheel, D, ixed on a shaft, E,

thence around three guidewheels F G H arranged as represented in the drawings. The guide-wheel F is xed on a`driving-shaift, I, which carries a pinion, .0, that engages with a toothed sector, d, fixed on a horizontal shaft,f. From the sector d an arm, g, is extended in llthranner as represented in lig. 2. *AA pin, L, projecting laterally from the said arm,'enters a slot, z', made in a plate, c, which is fastened vertically to the'side of the carriage B.. i

When the two lshafts E and I are alternately put in revolution in the right directions, the carriage will be moved out by the endless chain, with a regular motion, and afterward, by means of the slottedplate 7c, the arm g, pin h, sector d, and pinionrc, will be moved at a quick velocity, and gradually arrested and held, so that it cannot rebound on the rails.

I claim the combinatiom'for operating the carriage, ofa mule in manner as set forth, such consisting of the chain C, and its impelling and guide-wheels, the Vpinion c, toothed isetoroharxn g, the pin h, andthe slotted plate 7c, the whole being arranged substantially as specified.

JOHN GUMNOOK.
